Highly suspicious, everyone is downstairs.....except her upstairs and there are grills on the window, yet she have time to unlock the grills to escape and none of the killers chased her.

If all the family are downstairs, why is her bedroom locked? She said they tried to kick open the door. Did she know they are coming in?

Those are not her kids, maybe she found a lover and wants to get rid of this family? Maybe for insurance money? After all, they re not her kids.

So, is it a gangster killing or the wife or the neighbour? 24 hours is almost up!
